What are mega-tsunamis? What happens when you have millions of years of rain? Visual effects, location filming and stunning aerial photography bring viewers back 4.5 billion years to enjoy a unique window on our world. How the Earth Was Made peels back time like layers of rock to reveal the origins of the place we call home.

    The miner says "1,750 feet" below the surface. The captioning reads 750 feet below the surface.

    Evolution did it if you believe the Globalist .

    “The More You Know” 💫

  • shawn malbrough on February 2, 2022

    These lakes are less than 500 years old. The Spanish mapped the area to have several huge cities and branching rivers where we now have 5 giant lakes. The natives have maps showing the same. His-story is a lie, made evident by cartographers.

  • lydia ernst on February 2, 2022

    Ha! Seriously. Everything they taught us in this corporate dumphole is a lie. Apply that to everything they say as well.

  • Robert Taylor on February 2, 2022

    Well if you believe the bible, as I do, it’s not millions of years old but thousands
    The Lord clearly says he flooded the Earth which he did, so yes there was ocean here at one time
    The run off of this is what made the mountains and river systems
    More and more scientist are understanding the truth of the bibles timeline
    Also when Yellowstone volcano blew up and created the ice age, this played a big part in land formation
    In run off of this ice age
    So be listening , with a grain of salt when they , the scientist, claim millions of years, it was most likely thousands folks
    We don’t have thousands of years left folks, if you read the bible the end times are coming true so fast it is incredible,

  • Denise King on February 2, 2022

    wow, im soo looking forward to the paradise coming, Gods kingdom. the bible says in revelation 21:3,4 God will be with us again, and he will wipe every tear from our eyes and death will be no more neither will mourning or outcry or pain be anymore the former things have passed away. in the bible it says if we tell others, we can save both ourselves and those who listen to us. and that it makes our hope more sure. ephesians chapter 6 says to open our mouths and speak with boldness the goodnews of Gods kingdom the paradise.

  • Maytag Mark on February 2, 2022

    Some day there may well be a a geological event maybe an earthquake that will open the salt caverns up to the fresh water lakes.

  • Tom Johnson on February 3, 2022

    Lyle. God. Lyle. God. Who do I believe?

  • Tom Johnson on February 3, 2022

    I remember when lake Erie was born. It started as a divot in the earth. I peed in it.

  • Tom Johnson on February 3, 2022

    What these so-called archeologist's probably didn't even consider is the strong possibility that the early native American Indians invented the "shovel". They were so excited about these "shovels" that they had "shovel-a-thons". They dug and dug and piled all of the dirt in the middle. They noticed the pile looked like a "mitten". They dubbed the pile "Mitten-land" which in Indian speak would be Michigan. Then they all peed in the holes they dug. The rest is history. This all took place nearly ten hunnert years ago.
    You're welcome!

  • Christopher Shayne on February 3, 2022

    Sounds like a bunch of BS theory to me.

    Crustal rebound. MS Geology from WMU in Michigan.

  • Joe Granat on February 3, 2022

    This is the stuff that made your channel what it was. We need more documentaries less reality TV.

  • Damon on February 4, 2022

    So only Lake Huron and Lake Michigan have salt mines? I guess the salt under Lake Erie doesn't exist! All this mining in Fairport Harbor, Ohio, out under Lake Erie, is a sham. Morton Salt is mining what then? This mine is on the other end of Lake Erie from Michigan so it is not just an afterthought. Sorry but better research needs to be done.

    Also, what they keep calling the Niagara falls. It is called the Horseshoe falls which is in Canada. Niagara Falls is a couple thousand feet away on the southern rim. It is located in the United States. They shutdown the Niagara occasionally to slow the erosion. However the escarpment is called the Niagara Escarpment.

    full of sh%

  • CDF DeSantis on February 4, 2022

    Mustn't forget about the comet or asteroid that exploded above the Laurentide ice sheet at the end of the last ice age, either. The heat from the explosion would have melted billions of tons of ice, creating gargantuan floods. These floods ran off both east & west sides of the continent, as evidenced by the Scablands of the upper mid & north west. Some of the most intriguing evidence of the explosion are the Carolina Bays, found along the coast from MD to GA. They were formed by enormous chunks of the ice sheet being blasted off, & impacting the mid-Atlantic & southern coast. The Great Lakes region has played a significant role in the formation of North America, & will continue to do so as long as earth exists, providing us with a spectacular landscape to appreciate.

    Fascinating video.

  • steve hisey on February 4, 2022

    Wow, so there were several early generations of SUV's and campfires that caused repeated ice cap meltoff?

  • klacy5555 on February 4, 2022

    Another ice age coming in the future, what happened to "GLOBAL WARMING"

  • Kendall Smith on February 5, 2022

    I guess the impact crater under the west end of Ontario hadn't been discovered yet.

  • John Dienst on February 5, 2022

    Why do they never mention lake st Saint Clair ?

  • James Betker on February 5, 2022

    I was a rock hound in Chicago when young. We studied about the Great Lakes. And indeed they were formed by ancient glaciers. The Dolostone they talk about is actually Dolomite which is Calcium Magnesium Carbonate.

  • Jeff Routledge on February 5, 2022

    So if man is allegedly causing the ice caps and glaciers to melt due to "man-caused climate change" then how does one explain the glaciers melting to form the Great Lakes thousands of years before cars, industrialized society and those evil carbon emissions? Perhaps changing climates are simply a normal cyclical Earth process.

  • Joe Miller on February 5, 2022

    I was there and my hut kept moving. . Wtf. Lol

  • Joe Miller on February 5, 2022

    Bible folks doesn't see no reality. . .

  • Joe Miller on February 5, 2022

    My grandson dump truck I made for him. . Made the great lakes…….facts 👍

  • the life of FASTONY on February 5, 2022

    All that water in the Great lakes and no one had come up with a solution to bring some of that water to the west where there's a drought.. all that water from the Great lakes runs to the ocean…

  • Spencer Calvert on February 5, 2022

    If U think U learned how our world was made or if U understand our history on our planet in school think again. Good education means that U understand nothing yet. U need to learn how to learn. As a child I was worried what would happen once we learned everything 😂

  • James Boyd on February 5, 2022

    Learning is my favorite hobby…watching these videos are very interesting…so North America was just south of the equator..385 million years ago…

  • JJ Da Barber on February 6, 2022

    @ 11:51 whether it was thousands or millions of years ago the earth was matched together & overtime yes it spread apart, I'm continuing to rest of video now just had to throw in the biblical doubt

  • Shawn Webb on February 6, 2022

    the earth is moving 800mph..something is bound to move

  • Love Hate Sports on February 6, 2022

    They asked Indians and then made the video. 😂

  • Dan Peezy on February 6, 2022

    Don't get how they know all this

  • frank davis on February 7, 2022

    Hasn't proved anything to me one wild goose chase after another

  • David Cookson on February 8, 2022

    I live on Lake Michigan, last year the water hit record highs, this year 2021 it dropped 2 feet. I have a sign in my house that says welcome to Lake Michigan where everyday is a new adventure. I live in awe of these magnificent bodies of water.

  • Peaceman67 on February 8, 2022

    The Glacier was just to the North of the border 12k yo..

  • Adam Steidl on February 9, 2022

    I'm waiting for them to mention what happened in between the ice ages you know ice just doesn't disappear it makes water! Lots of flowing water. And water can scour rocks as well as ice can. I'm taking vast flooding created the lakes and then the ice maybe just enlarge them a little bit

  • Steve Ketterer on February 9, 2022

    Great video, but I have one discrepancy to question:
    "[Lake Superior's] floor is the lowest place on the North American continent." I thought Death Valley was the lowest?

  • Jason Corbin on February 9, 2022

    Wow, a scientist coming up with a reason for lake levels dropping other than global warming. Never thought I'd see that.
